Well....what a surprise!! Every bit of science we have about heat stress thresholds in Bos taurus cattle indicates that they have the potential for heat stress crossing the Equator...fatten them up, ensure they are over 600kg...and then send them from Portland....mid winter....after a voyage from Freo in May has already failed???

The Dept is currently asking for submissions on Heat Stress Risk Assessment in sheep to the Middle East.....perhaps they should do the obvious thing and reassess their totally flawed HSRA for cattle (to any location) also.
